White Matter Microstructure and Cerebral Blood Flow in 43 Healthy Subjects

A collection of neuroimaging data from 43 healthy subjects with a mean age of 26.3 years. It includes diffusion tensor imaging and arterial spin labeling measurements to analyze cerebral blood flow and its relation to white matter microstructure. The analysis was performed using tract-based spatial statistics across subjects and white matter tracts.

Use Cases

• Analyze the correlation between cerebral blood flow and fractional anisotropy across subjects in specific white matter tracts like the splenium of corpus callosum.
• Investigate the negative correlation between radial diffusivity and cerebral blood flow across subjects in regions such as the posterior thalamic radiation.
• Examine the positive correlation between cerebral blood flow and fractional anisotropy across different white matter tracts within individual subjects.
• Perform voxel-wise statistical analysis of cerebral blood flow and anisotropic diffusion using tract-based spatial statistics.

Strengths

• Data from 43 healthy human subjects provides a sample for neuroimaging analysis.
• Includes paired measurements from two established neuroimaging techniques: diffusion tensor imaging and arterial spin labeling.
• Analysis performed using standardized tract-based spatial statistics methodology.

Limitations

• Sample size of 43 subjects may limit statistical power for detecting subtle effects.
• Subject cohort is homogeneous (healthy, mean age 26.3 years), limiting generalizability to other populations.
• Specific data file formats, column structures, and raw data sizes are not described.
